Preparation and Feeding Information
  • PWT 1082 is a single component emulsion polymer that must be pre-diluted in water before use.
  • In most cases, this product should not be applied neat.
  • One method for dilution is adding the neat polymer into the vortex of a mixed tank at a concentration between 0.25 - 1.0% polymer (0.5% is optimum) by weight.
  • The polymer can also be injected through a number of commercially available systems that provide in-line mechanical mixing.
  • Polymer solutions should be aged for 30-60 minutes prior to use for best results.
  • Solution shelf life is 8-16 hours.

Packaging & Availability

Storage & Handling

Storage, Stability and Handling Information
  • Suggested in-plant storage life is one year in unopened drums.
  • For best results, store at 50-80°F.
  • Bulk tanks should be mixed by periodically recirculating the contents bottom to top.
  • Bulk tanks can also be fitted with an agitator type mixer that reaches the bottom 2 feet of the tank.
  • Do not allow emulsion polymers to freeze.
  • Should freezing occur, allow the product to thaw thoroughly in a heated area and mix well before attempting to use it.
  • For spills of PWT 1082, sprinkle salt, vermiculite or equivalent absorbent over the spill area and sweep the material into approved chemical disposal containers.
  • Do not spray water onto a spill because the resulting gel is very difficult to clean up.
Materials of Construction
  • Cross-linked polyethylene, fiberglass, stainless steel or lined steel are the preferred materials of construction for bulk tanks.
  • Avoid natural rubber and Buna-N gaskets as these materials swell when placed in contact with neat polymer.
  • Unlined mild steel, black iron, galvanized steel, copper or brass are not recommended in any part of the feed system.
  • Stainless steel, Viton or Teflon are the best choices for pump heads. For feed lines, polyethylene, PVC or reinforced Tygon tubing is recommended.
